If the print screen is anything to go by, I'd say you should keep a more consistent theme. You have an ice environment, with a tree from a forest world, as well as lava. Lava melts snow, and trees don't grow on ice. If you keep that in mind you should be good to go.

My name is Jason. And I am an amateur artist. When I have the time, I try working on revamping some of the supertux art.

"I get where you're coming from, but it's all about atheistic. In general, consistency is key. Also, a nice looking level will draw more people in to play it."

No offence, but you couldn't be more wrong. No one cares about consistency. Consistency is boring. I like the idea of trying to blend the elements. Although I do admit it could be a bit more effective, its a pretty nifty effort at trying to make a level that stands out. Blending of ice and lava doesn't have to make sense, so therefore it is left to the player to wonder how cold the ice is or etc. It's about sparking imagination, not just wanting people to run past the finish line.

That being said, its a nice level. I do think if you're going to blend the elements it'd be better if you took more care with it rather than sticking a random tree under ground. For a day though, its decent.
